[Her cheeks flush red, because yes, she does think Jim is attractive. But she hasn't really looked beyond every now and then, and so she gets flustered, and bristles at Jack's question.]

So not gonna answer that! You'll just have to find out for yourself. He's the one I'm living with, though. And really, it's not what it sounds like. I don't think he'd ever look at me that way, not in a million years. [Kind of like every other man in her life, it's okay. She's got it under control.]

And you better not look at him that way, either.

[Because she does not want to be jealous of Jack and Jim liking the other more than they like her, and she knows she will and it would be just awful.]
